Can you find a training place that used American Pet Dog Trainers? I don't think much of PetsMart and PetCo type places. At some, the person has passed a written test to qualify for the job - and never owned a dog! At a proper dog training facility, the trainers have dog(s) they work with in Agility, Herding, Flyball, something so they are used to reading dog body language. they will teach you how to read YOUR dog's body language.

Maybe you can find a place on this site:

I agree w/ Karen, the move has been a huge trigger in starting the fighting. And yes, Bostons have been bred as companion animals for generations now, so don't worry about that.

When you spend time with Prairie's teeth issues, do you then spend time with Biscuit? You should!

To answer your question, yes absolutely treat and praise good behavior! Once reason I like APDT is they only use positive reinforcement. If both dogs are lying down calmly, hey, let them know you approve!

When they are fighting, of course you do what you have to do to separate them. Then they should BOTH go in a time out. Do you have crates? I don't crate train, per se, but I DO have crates I can use for time outs. Start at 3 minutes. And while they are in time out, do not make eye contact with either dog. Completely ignore them both.

I am sorry Biscuit got hurt, thank goodness it was not more serious. I am sure you have to check them over after a fight, but that should be quick and into time outs for both of them. If you do time outs 3 or 4 times a week, then move it up to 5 minutes. You can set a kitchen timer. When times up, let them out but do NOT make a fuss over either of them.

Finally, I am sure you are also very busy with the move, unpacking, sorting. Are the dogs getting regular exercise? A tired dog is less likely to fight.
